Problems solved by technology

[0005] The invention provides a new type of anti-seepage concrete prefabricated pipe pile, one of which is to have the characteristics of fixing, sealing and preventing water seepage at the joints of the columns, so as to solve the problem that the welds are easily damaged and the joints are easy to seep so that the pipes The inside of the column is corroded; another purpose is to solve the problem that the column needs to be hit by an external force to squeeze the column downward, which leads to the problem that the column will break and crack when it is pressed down , to achieve the effect of adding a soil-breaking cone at the bottom of the column to increase the efficiency of soil-breaking

Abstract

The invention discloses a novel anti-seepage concrete prefabricated tubular pile, and relates to the technical field of anti-seepage concrete pipes, the novel anti-seepage concrete prefabricated tubular pile comprises an anti-seepage concrete pipe, the anti-seepage concrete pipe comprises a concrete tubular column, and the outer surface of the concrete tubular column is movably sleeved with a gap extrusion sealer; the inner surface of the bottom end of the concrete pipe column is movably sleeved with a downward extending ground breaking head, the concrete pipe column comprises a waterproof layer, and a high-strength concrete layer is poured on the inner surface of the waterproof layer. The concrete pipe column is fixed through the lock head, then the threaded column is rotated by inserting the rotating rod into the hole, gaps in the surface of the concrete pipe column are sealed in cooperation with the arc-shaped soft block, a foam expanding agent is injected into the hole for sealing, and the characteristic that the column connecting position is sealed is achieved; the problem that the interior of the pipe column is corroded due to the fact that water easily seeps into the butt joint due to the fact that welding seams are easily damaged is solved, and the effect of sealing the column joint is achieved.

Description

technical field [0001] The invention relates to the technical field of anti-seepage concrete pipes, in particular to a novel anti-seepage concrete prefabricated pipe pile. Background technique [0002] In engineering applications, prefabricated concrete pipe piles need to be composed of one to three concrete pipe pile sections. During construction, the first concrete pipe pile section is first pressed into the soil, and then the second concrete pipe pile section is docked with the first concrete pipe pile section. , and then the third concrete pipe pile section is docked with the second concrete pipe pile section. The method of pile connection is generally to connect the end steel plates on each concrete pipe pile section through electric welding to complete the joint of each concrete pipe pile section. Butt assembly between. There are following problems at prior art: [0003] 1. At present, in the process of sinking the butt pipe pile, the weld seam is easily damaged, whi...
